The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the ... When the plastic strip is rubbed on the skin, electrons from the skin are ...

The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

For the first time, scientists have successfully mapped the shape of an electron while it moves through a solid. This ...

Neutrons have no charge. Protons are positively charged ... deuterium (hydrogen-2) and tritium (hydrogen-3): if the atom loses one or more electrons, it becomes a positively-charged ion if ...

Key fact Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen ... there are no electrons There are 30 ...

You'll start with a hydrogen atom, which contains one proton and one electron. To build other atoms, just add protons, neutrons, and electrons. By the way, you'll need to create each proton and ...

A physicist explains how atoms arrange themselves into molecules – and how scientists are able to image these tiny bits of ...
